Doodia R.Br.

Sori in 1–2 (rarely 3) rows, rather short or sometimes later confluent, 1 in each areola attached on the inner side of the veinlet or veinlets parallel to the costa (Fig. 23). Veins areolate in the fertile fronds and most of the sterile fronds, rarely free in the latter Doodia
Pinnae in the lower third of the frond or almost all the pinnae very shortly stalked. Sori distinct or confluent. Fronds submembranous to coriaceous, uniform to very dimorphic
Plants decumbent or subdecumbent. Pinnae stalked in the lower half of the frond. Fronds submembranous to subcoriaceous, often very dimorphic
Fronds divided for the greater portion of the lamina but often with an elongated apical pinna, subdimorphic to very dimorphic. Widespread. RF and moist shady places on banks, often near creeks and waterfalls Doodia caudata
Fronds undivided for the greater part, with a few, short, broad, pinnae towards the base. Cumberland Plain and lower Blue Mts. RF margins or open forests. Uncommon Doodia linearis
